1 CCNA 1 v5.0 R&S ITN Final Exam Refer to the exhibit. The network administrator enters these commands into the R1 router: R1# copy running-config tftp Address or name of remote host [ ]? When the router prompts for an address or remote host name, what IP address should the administrator enter at the prompt? Which three statements characterize the transport layer protocols? (Choose three.) TCP uses port numbers to provide reliable transportation of IP packets. TCP and UDP port numbers are used by application layer protocols. TCP uses windowing and sequencing to provide reliable transfer of data. TCP is a connection-oriented protocol. UDP is a connectionless protocol. UDP uses windowing and acknowledgments for reliable transfer of data.
